1 Refrigeration & limate omponents Solutions 4.1 n Applications Refrigerant filtering and drying, and acid neutralization for refrigerating and air conditioning installation liquid lines. The filter driers receivers provide a permanent reserve of dehydrated and filtered refrigerant, for a better supply of the expansion valve, whatever the operating conditions. The filter drier receivers are particularly suited to low capacity installations that operate with a thermostatic pressure relief valve and that are equipped with an air-cooled condenser or a plate condenser. receivers fit perfectly within the heat pump systems. ustomized product Standard product n Functional features Products are compatible with Fs, HFs, HFs, O 2 s, as well as with their associated oils and additives. Products are designed for use of non-hazardous refrigerants from group 2 of PED 97/23/E. To use components with fluids of the hydrocarbon group 1 Propane R290, Butane R600, Isobutane R600a, Propylene R1270 with HFOs and transcritical O 2 and for a RANKINE organic cycle application, contact technical department. Product classification in E categories is performed using the PED 97/23/E table, corresponding to a volume-based selection. Hermetically sealed outer steel enclosure with paint to ensure a high resistance to corrosion. Filtering at outlet preventing propagation within the circuit of particles bigger than 25 microns, with a very low pressure drop. No desorption, even at high s. Possible customization on request: Drying capacity Receiver volume Specific unions (O-RING, ORFS, etc.) Adding of an indicator with or without hygroscopic paper on the receiver part Aluminium casings and connections (weight optimisation) Stainless steel casings and connections (resistance to corrosion and at low s) onnections to braze, 100 % copper Model «Bi-flow». n advantages Maximal pressure: 46 bar. ompared to an assembly with two separated components (filter drier + receiver) è Space gain on the installation è Optimisation of assembly time è 2 connections to be screwed or brased instead of 4 ; therefore, reducing the risk of leakage Great drying and acid neutralization capacity at all s, thanks to a rigorous selection and a judicious mix of the chemical agents present in the filter driers (activated alumina in order to neutralise the acids and molecular sieves to adsorb moisture); the volume of free-grains drying agents used in a filter drier is greater than that present in an equivalent model with a solid core. Initial drying capacity guaranteed by a 200 oven drying and airtight sealing. Drying ensured for the subcritical O 2 applications at low s. A dispenser located at the intake ensures optimal distribution and permanent treatment of the whole refrigerant, inside the filter drier receiver. The copper-plated steel connections facilitate the brazing and allow using brasing alloys with a low silver percentage. GOST certified products.

2 4.2 Refrigeration & limate omponents Solutions n Warning Before selecting or installing any component, please refer to the chapter 0 - WARNING. n General assembly precautions The installation of a component in a refrigeration system by a skilled professional, requires some precautions: Some are specific to each component, and in this case, they are specified in the REOMMENDATIONS SPEIFI part defined hereafter ; Other are general to all components, they are presented in the chapter 115 GENERA ASSEMBY PREAUTIONS. The recoendations relating to the components for the subcritical O 2 applications are also developed in chapter 115 GENERA ASSEMBY PREAUTIONS. n Recoendations specific to the filter-drier receivers receivers are to be mounted on the liquid line between the condenser and the expansion element. The refrigerant flow direction is indicated by an IN mark in the inlet shell of the filter drier and by an arrow on the filter drier tag. It must be necessarily respected. Mounting of filter drier receivers should always be performed vertically, refrigerant inlet up, for proper use of the receiver part. We recoend the use of a brasing at 10 % silver minimum for the brasing of the copper coated silver unions. Be careful to properly select the solenoid valves located downstream of the filter driers; their over-sizing could cause liquid haer phenomena hindering the filter driers mechanical behaviour; protection of regulation elements located upstream of the evaporator should be performed with FITRY dirt filters (refer to chapter 11); these liquid haer phenomena can originate from other sources, in longpiping installations. Never install the filter driers in an area of the circuit that can be isolated. Never trap the refrigerant in its liquid state (between a check valve and a solenoid valve, for instance). The filter driers must be changed : è after each intervention on the installation requiring the opening of the circuit è when the liquid indicator (VY or VYS) indicates an abnormal humidity content è when the pressure loss measured in the filter drier is too high è at least once a year as a measure of precaution A filter drier saturated in humidity no longer retains the water molecules which circulate then in the circuit ; these molecules in contact with other materials and with the POE oils which are very hydrophilic are liable to form acids which can be fatal for the installation ; therefore, it is very important to use filter driers containing activated alumina in order to neutralise as rapidly as possible the acids present in the circuit and not dewatering filters with only 100 % of a molecular screen. efficiency and refrigerant moisture content should be checked using VY or VYS liquid sight glasses (refer to chapters 9 or 10). Make sure that the piping can support without deformation the weight of the filter drier ; otherwise, provide for the attachment of the filter drier with a clamp on a stable part of the installation. Example of a selection of a for the drying part of the product : see example of a selection of a DY filter drier in chapter 1. For the liquid tank part of the product, use the usual methods for determining the coolant fluid storage volume by taking into account all the parameters related to the user s application.
